If we compare scripture with scripture, and read that part of Psalms 91:1, which evidently and plainly refers to Christ, I think the likeness between that scripture and this, may allow us to suppose that it is the ever blessed Jesus, as the head and surety of his church, who is here speaking. Psalms 91:14-16.
